Many a man set north with a golden glimmer in his eye and settled instead for striking silver – most didn't complain too much considering it was far more lucrative than what they left behind. This shirt would have been prized in any mining camp as the 3.6-oz 94% Nylon plus 6% spandex gives ease and durability by the spade load and, best of all, a Polygiene® silver chloride treatment is bonded into the fabric to kill odor-causing bacteria and keep this shirt smelling clean. UPF 50+ sun protection, Armpit Gussets let you reach, vented back for cooling, plus flapped chest pockets with zippered Napoleon pockets behind for security. Triple stitched main seams for durability. Even a chamois wipe on the shirt tail to keep your glasses clean.
